The finite blocklength (FBL) communication has been studied for quite some time for the fifth generation of cellular networks (5G). Though, the research in FBL is still in early stage due to the fact that 5G requires high reliability of almost 99.999

The spectrum sensing is a vital stage in cognitive radio networks. The performance of energy-based spectrum sensing scheme degrades under noise uncertainty, which can be improved by covariance-based sensing methods. In this paper, a double threshold-
